Permanent Cross Eyed

Explanation
Cross eyed is when you have one or both eyes turning inwards towards the nose.
But there is an actual disorder that includes being "cross eyed"

How it Happens
Cross eyed disorders also know as a strabismus. A strabimus is when the eye doesn't line up correctly with the other eye. When one eye moves, the other does not move in unison with it.
Causes

• It may be present at birth (1 in 25 infants born in the US have strabismus.)
• caused by illness.

In most cases, the only effective treatment for a constant eye turn is strabismus surgery.

Symptoms:

• Abnormal alignment of the eyes (eyes appear crossed)
• Eye movements are not coordinated
• Double vision
• headaches

Diagnosis:

• Eye exam
• Visual acuity testing
• Retinal exam
• Neurological exam
• Eyes appear crossed
  • Eye appears to deviate toward the temple
  • Eye movements are not coordinated

Treatment:

• Eye exercises to train them to work together and more effectivley
• eye patch
• medication injections- Botox, weaken the muscles around the eye to improve alignment
• surgery -changing length or position of the eye muscles
• Eye glasses or contacts

Types:
Esotropia:

• An eye that turns inward, toward the nose

Exotropia:

• An eye that turns outward, toward the temple

But, if you are crossing your eyes for the fun of it, your eyes cannot permanently get stuck in the cross eyed position. Although, crossing your eyes for a long period of time will strain your muscles and cause soreness.

Optics and Light With Crossed Eyes
When your eyes are crossed, your vision is unfocused and blurry.
